在matlab下实现了z变换，给出了分析、源文件和输出的零极点图(Matlab achieved in the z transform, gives an analysis of the source file and output zero-pole diagram)

一个坐标系转换的类，参考系：WGS-84椭球体参数；功能：笛卡尔坐标系、大地坐标系、站心地平坐标系（线坐标形式）、站心地平坐标系（极坐标形式）之间的互相转换。(A coordinate transformation class reference system: WGS-84 ellipsoid parameters Function: Cartesian coordinates, geodetic coordinate system, Station Local coordinate system (line coordinates), Station Local coordinate system (polar form) of conversion between each other.)

Performance and Cost Evaluation of IEEE 802.11g and 802.3i Protocols for Network Connectivity at a University Campus using OPNET Simulation

计算暂态稳定问题，应用隐式梯形算法，算出各时刻发电机角度(Calculation of transient stability problem, apply the implicit trapezoidal method )

本程序用小波包3层分解把信号分解成8个频段的信号。(The procedures used 3 layer wavelet packet decomposition of the signal into the eight-band signal.)

应用一般最小二乘法与递推式最小二乘法对二阶系统进行参数辨识(RLS)

QWT code for Disparity Estimation.

该程序是在flac下运行的，没找到flac，所以用matlab表示了，供岩土力学研究方向学习(The program is run under flac, did not find flac, so use matlab shows for rock mechanics research study)

一种结合高斯分布的改进的QPSO,MATLAB 代码，吸引因子使用了高斯分布，加强了代码的全局搜索能力。(A combination of Gaussian distribution improved quantum particle swarm, MATLAB code, attracting factor Gaussian distribution, strengthen the global search capability of the code.)

实现希尔伯特-黄变换的功能，并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数（IMF），然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。(The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear.)
